A life cycle assessment (LCA) was conducted to evaluate the total environmental impact of state-of-the-art waste-to-energy (WtE) in Belgium with respect recovered energy utilization and addition carbon capture storage (CCS). Four output scenarios were modeled on Umberto LCA software using primary data mass flows surrounding six incinerators at considered WtE plant predefined processes from Ecoi...

The key ideas in the theory of broadcast channels are illustrated by discussing some of the progress toward finding the capacity region. The capacity region is still unknown.

Cellular phone users in Korea can watch TV using their mobile phones. The new multimedia service for the mobile users is called Digital Multimedia Broadcasting (DMB). DMB is a process of broadcasting multimedia over the Internet or satellite that can be tuned in by multimedia receivers or players. There are two competing DMB technology standards in South Korea: Terrestrial DMB and Satellite DMB...

In this paper a scheduling policy is presented which minimizes the average delay of the users. The scheduling scheme is investigated both by analysis and simulations carried out in the context of Orthogonal Frequency Division Multiplexing (OFDM) broadcast channels (BC). First the delay optimality is obtained for a static scenario providing solutions for specific subproblems, then the analysis i...

Past petroleum-extraction activities in Ecuador have contaminated its Amazon region. To assess the environmental impact attributed to remediation regarding cleanup of these oil spills, two scenarios were studied according Life Cycle Analysis methodology: (1) No-action, which means leave contamination place without any further action and (2) Environmental remediation, where environmental-load re...

GOAL, SCOPE AND BACKGROUND Humans now strongly influence almost every major aquatic ecosystem, and their activities have dramatically altered the fluxes of growth-limiting nutrients from the landscape to receiving waters. Unfortunately, these nutrient inputs have had profound negative effects upon the quality of surface waters worldwide. This review examines how eutrophication influences the bi...
